Does Best Buy sell 3 in one file folder within one folder. Each of the 3 sides of the folder has the works to attach a two hole punched document.

Agreed

I'd suggest you try OfficeMax for that. I don't think Best Buy carries that sort of item.

For two hole punch on the top of the page documents I'd only suggest Office Max honestly. For the three hole punch on the side documents you're better off trying OfficeMax, any Walmart, Target, any Dollar Tree, any Family Dollar, any Dollar General, Big Lots, Dillons in Fairlawn Plaza, Dillons on Highway 24, or Dillons on California. If you like being ripped off and overpaying Walgreens or CVS 😂. There are clearly more options for the three hole punch on the side documents. Good luck!
